Definitions

  • the present invention refers to a seat for a vehicle.
  • the invention refers to an aircraft passenger seat or an automotive passenger seat.
  • U.S. Pat. No. 9,073,453 describes a seat including a seat pan having a seat pan front edge and a seat pan rear edge.
  • the seat pan front edge defines a first pivot point and the seat pan rear edge defines a second pivot point wherein the first pivot point remains in a substantially fixed position for each of the positions.
  • the European Patent 2,420,404 defines a vehicle seat comprising a vehicle seat vibration device and a suspension device.
  • the present invention seeks to improve a seat for a vehicle to bring the seat into one or more positions, e.g. into a taxi, take-off and landing position (also "TTL” or “TT&L” position called), an inclined position or a sleeping position.
  • a taxi, take-off and landing position also "TTL” or “TT&L” position called
  • TTL taxi, take-off and landing position
  • TT&L TT&L position
  • the object is achieved by a seat for a vehicle according to claim 1.
  • the disclosure provides a seat for a vehicle, in particular an aircraft passenger seat, wherein the seat comprises a seat support structure which is connected to a base structure.
  • the seat support structure provides at least a seat pan having at least a seat pan frame with two lateral seat pan sides, a front seat pan side and a back seat pan side, a backrest having at least a backrest frame that is pivotably mounted to the back seat pan side at a backrest pivot axis, a leg rest having a leg rest frame that is pivotably mounted to the front seat pan side at a leg rest pivot axis.
  • the leg rest is configured as a calf rest.
  • the seat pan, the backrest and the leg rest are articulated with respect to each other such that the seat is positionable into at least one of a taxi, takeoff and landing position, a comfort inclined position (inclined position) and a sleeping position
  • the seat is locked to the base structure by at least one latch mechanism when the seat is in the taxi, takeoff and landing position.
  • the disclosed latch mechanism provides a temporary mechanical fixation between the seat support structure and the base structure and an aircraft floor in the taxi, takeoff and landing position.
  • a compensation of forces in different directions which affect the seat can be substantially provided by the latch mechanism.
  • compressive and tensile forces will be substantially compensated.
  • the latch mechanism is configured as at least one latch element and at least one pawl element, wherein at least one of the latch elements is provided by the base structure and at least one of the pawl elements is provided by the leg rest and/or at least one of a single lever which is arranged on each of the two lateral seat pan sides, or vice versa.
